To a whom it may concern.

Be it known that we, CYRUS C. SHIGLEY, residing at the village of Hart, county of Oceana, and SHERMAN H. PAXTON, residing at the city of Grand Rapids, countyof Kent, State of Michigan, citlzens of the United States, have invented certain new and useful Improvements in Record-Rolls for Phonographs, of which the following is a specification.

This invention relates to improvements in record-rolls for phonographs.

The objects of this invention are, first, to

V record-roll for. phonographs which will produce loud, distinct, and full tones, which is simple in structure, economical to produce, and durable in use; secimproved record-roll.

refer to similar parts 0nd, to provide an improved record-roll for phonogr'aphs adapted to be used upon a mandrel or'shaftof even diameter'from end to'end.

Further, objects and objects relating to structural details will-definitely-appear from the detailed description to follow. b We accomplish the objects of our invention Y following specification.

The inventionis clearly defined, and point ed outin the claims. I

A structureembodying the-features of our invention-is clearly illustrated in-theaccompanying drawings, forming a part of this sp ecification, in which-.-

nographic record. This shell is cylindrical in form and is provided with inturned flanges a a at its ends. The shellA is provided with a backing or filling A of some suitable plastic material, preferably plaster-of-paris, which is preferred, as it is comparatively light and is adapted to be poured or cast and is also adapted to set or harden at ordinary tem eratures.

A mandrel or shaft sleeve 0 is embedded and retained inthe filling or backing material A. This sleeve'is adapted to he slipped upon a mandrel or shaft D, such as is illustrated in Fig. 5. This shaft is of substantially even diameter from end to end, except for itsbearing-pivots, so that the record-r0 ls may be adjusted to any position thereon. The sleeve 0 is provided with spiral corrugations 0, which when embedded in the filling material prevent its withdrawal. The sleeve 0 is slitted at each end, as clearly appears in Fig. 4, and the slitted portion deflected inwardly on the mandrel or shaft D. I

Our improved phonog illustrated herein is particularly use on phonograph-machines such as illustrated and described in Letters Patent to Cyrus 0. Shigley, issued same is, however, relations. r

In the manu acture of our improved record-roll the record is first made upon the shell A. A rod-like standard B is provided. We also provide a pair of conical cores B B for the ends of the record-rolls. These cores are provided with central holes adapted to receive the standard B, which effectively centers them in relation to each other. The core B is secured to the standard B by the setscrew 1). Athumb-screw b is provided for securing the core B to the standard.

In forming our improved first'secure the core B upon thev standard, which is suitably supported, preferably in an upright position. The sleeve C is then slipped upon the standard and forced down The filling or backing material A is then poured or cast intothe shell and the core B pressed into the same and secured in position by means of the thumbscrew 1). The filling material or backing isthen allowed to set or harden. By forcm the core B into position the filling materia May 5, 1903. The adapted for use in other raph record-roll as adapted for record-roll we 9 3 shaft sleeve having slits therein, said slitted might be used.

Although we prefer to form our improved record-roll as we have illustrated and described on account of its structural simplic ity and economy, we are aware that the same may be varied considerably in structural details without departing from our invention.

Having thusdescribed our invention, what we claim as new, and desire to secure by Letters Patent, is I 1. In a phonograph-record, the combination of an outer shell of celluloid or other suitable material, having inturned flanges at its ends; a corrugated mandrel or shaft sleeve having slits therein, said slitted portions being deflected inwardly; a suitable plastic material molded or cast within said shell about said sleeve; and a mandrel-shaft D, all coacting for the purpose specified.
